Lenox 3084818X – Frequently Asked Questions

1) Will a Lenox 18-inch hole saw extension fit my drill if I only have a 1/2-inch chuck?
Yes. The Lenox 3084818X extension is an 18-inch arbor extension built around a 1/2-inch chuck system, so it mounts in a 1/2-inch drill chuck and holds the hole saw on the other end. Tighten both ends fully before you start the cut, since the extra length magnifies any slip.
2) How deep an assembly can I drill through with this Lenox extension?
The extension itself adds 18 inches of reach, and the overall part measures 3 x 0.9 x 21.7 inches, so your usable depth is the 18 inches of shaft minus whatever the chuck jaws grip and the depth of the hole saw cup. That is enough for stacked wall assemblies, drilling through multiple joists, or reaching a stud bay from outside the finished wall.
3) Does the Lenox hole saw extension come with a pilot bit, or do I need to buy one?
It ships with a lead screw tip already fitted, plus an extra lead screw and a wrench for changing it out. You supply the hole saw. The aggressive lead screw is what pulls the saw into the material, so keep a spare in the pouch, since the pilot is the part that gives up first on long runs.
4) Can I use this extension for drilling through nail-embedded wood in a remodel?
The cutting edge is high speed steel, which Lenox specs for durability in nail-embedded wood and other tough material. For retrofit work where you are going blind through old framing, that is the right pick over a plain carbon pilot. The flutes clear chips as you go so the shaft does not pack up in a deep hole.
5) Is the Lenox 18-inch extension heavy enough to be awkward overhead?
It weighs 1.19 lbs on its own. Add a drill and a large hole saw and the mass sits 18 inches out from the chuck, so overhead or ladder work puts real leverage on your wrists. Most electricians run it with a two-handle drill for that reason.
6) Why does the bit stick in the hole after drilling, and does this Lenox arbor fix that?
Binding on withdrawal is the usual complaint with long arbors. The Lenox 3084818X uses a chamfered edge design specifically so the bit pulls back out of the cut easily once the hole is through, which is what keeps you from having to reverse the drill and work it free in a deep assembly.
7) Does the Lenox hole saw extension need its own power source or battery?
No. It is a non-energy-using accessory, a pure mechanical arbor extension that runs off whatever drill you put it in. Nothing to charge, nothing to plug in.
